DETAILED DESCRIPTION Overview

Embodiments of the present invention now will be described more fullyhereinafter with reference to the accompanying drawings, in which some,but not all embodiments of the invention are shown. Indeed, theinvention may be embodied in many different forms and should not beconstrued as limited to the embodiments set forth herein; rather, theseembodiments are provided so that this disclosure will satisfy applicablelegal requirements. Like reference numerals refer to like elementsthroughout.

In the development of new medical procedures, medications, and othertreatment options, rodents (i.e., rats, mice, etc.) are often utilizedas a medium for verifying the safety and effectiveness of newdevelopments before administration to human subjects. Rodents are oftenutilized for their convenience and their genetic similarity to humans.As mammals, rodents share similar biological processes and systems totheir human counterparts and, therefore, are an effective indicator asto the likelihood of success associated with a proposed medicalprocedure.

In many surgical environments, a surgical table or apparatus is utilizedto support and secure the subject during a procedure. A surgical tablemay secure a specimen at a desired position and may limit motion of thespecimen to ensure that the procedure is completed properly.Additionally, anesthesia is also often utilized to ensure that thespecimen remains in a desired position. Traditionally, a separateanesthetic supply device (e.g., free standing) is utilized to deliver ananesthetic to the specimen resulting in various tubes and cords freelyhanging to connect the anesthetic supply device to the specimen. Inthese circumstances, navigation around the specimen during operation istedious and creates the risk of disturbing the specimen. Additionally,repositioning of the specimen during a procedure, using conventionaltechnologies, requires releasing the specimen from the surgical tableand/or moving the physician about the surgical table.

Embodiments of the present invention that are described hereinbelowprovide a rotatable surgical table for processing a specimen. Inaddition, embodiments of the present invention also provide forsupplying an anesthetic to the specimen via the surgical table, asopposed to a separate device, such that the specimen may receivecontinuous anesthetic during rotation of the surgical table. In additionto rodents and small animals, one of ordinary skill in the art willappreciate that the devices and methods discussed herein may be scaledto accommodate any patient or specimen.

For the sake of clarity and convenience of description, the embodimentsthat are described herein are made in reference to various components,elements, members, or the like that allow and/or maintain fluidcommunication. As used herein, the term “fluid” may refer to asubstance, such as a liquid or gas, which does not have a fixed shapeand is capable of flowing. By way of example, in some embodimentsdescribed below, a gaseous anesthetic may be considered a fluid, and maybe administered to a specimen via various respective channels in fluidcommunication with one another (e.g., an anesthetic supplied to a firstbase channel in fluid communication with a first platform channel).

Rotatable Surgical Table

Some embodiments described herein include a base member and platformmember. The base member and the platform member may abut one another andbe configured such that the platform member may rotate relative to thebase member. The platform member and base member may each define one ormore channels where the one or more channels of the platform member arein fluid communication with the one or more channels of the base member.In some embodiments, the platform member and the base member may eachdefine two channels. In such an embodiment, a treatment agent (e.g., ananesthetic) may be supplied to a first channel of the base member thatis in fluid communication with a first channel of the platform member.In some embodiments, a nozzle (such as, for example, a nose cone) may beaffixed to the top surface of the platform member such that a specimen(e.g., a mouse of other rodent) secured to the platform may beadministered an anesthetic. This nozzle may be in fluid communicationwith the first channel of the platform member. As described in furtherdetail below, some embodiments of the rotatable surgical table mayutilize the second channels of both the platform member and the basemember in conjunction with a reverse flow (e.g., vacuum suction) tocreate a self-scavenging system at the nozzle.

With reference to FIG. 1, an opaque top view of the base member 100 isshown with a first surface 105, gasket 110, a first base channel 120, asecond base channel 130, an inner annular chamber 115, an outer annularchamber 135, a first side port 125, and a second side port 140. Thefirst surface 105 of the base member 100 may be configured to abut thebottom surface of a platform member (e.g., bottom surface 500 in FIG.5). In some embodiments, the base member may define one or more annularwalls. These annular walls may define one or more annular chambers. Inthe example embodiment shown in FIG. 1, an inner annular chamber 115 andan outer annular chamber 135 are created by annular walls 145, 150defined by the first surface 105 of the base member 100. In order topromote sealing of the annular chambers and base channels from theenvironment, one or more gaskets 110 may be disposed on the firstsurface 105 of the base member 100.

The base member 100 may further define one or more channels to deliver afluid from an external source coupled with one or more side ports 125,140 to the respective inner annular chamber 115 or outer annular chamber135, or to remove fluid from the inner annular chamber 115 or outerannular chamber 135 via a respective one or more side ports 125, 140. Byway of example, the base member 100 shown in FIG. 1 defines a first basechannel 120 and a second base channel 130. As shown in FIG. 1, thesechannels may be located between a top surface (e.g., first surface 105)and a bottom surface (e.g., bottom surface 200 shown in FIG. 1) of thebase member 100. The base member 100 may be a solid body such that thefirst base channel 120 and the second base channel 130 are enclosed inand formed by the body of the base member 100. In some embodiments, thechannels 120, 130 may be formed in or on the base member 100 or mayinclude one or more separately-attached conduits. These channels may beconfigured such that a fluid may travel therethrough. In someembodiments, the base member 100 may be integrated into a larger tableor work surface such that the top surface of the base member is part ofthe larger table or work surface.

In some embodiments, the base member 100 may define one or more sideports (e.g., first side port 125 and second side port 140). The firstbase channel 120 may be in fluid communication with a first side port125. In some embodiments, this first side port 125 may be supplied witha fluid, such as an anesthetic or other treatment agent, that flows fromthe first side port 125 through the first base channel 120. The secondbase channel 130 may be in fluid communication with a second side port140. In some embodiments, a reverse flow (e.g., vacuum or other suction)may be applied to the second side port 140 such that a fluid may travelthrough the second base channel 130. In some embodiments, the secondbase channel 130 may receive the fluid (e.g., anesthetic or othertreatment agent) from the second side port 140, while the first basechannel 120 receives the reverse flow. In some other embodiments, bothof the channels 120, 130 may receive the fluid or reverse flow, eithersimultaneously or alternately, as required.

With reference to FIG. 2, a bottom view of the base member 100 isdepicted showing a second, bottom surface 200 and the respectivechannels 120, 130 therein. As shown in FIG. 2, the first base channel120 may be positioned so as to connect the first side port 125 and theinner annular chamber 115. Similarly, the second base channel 130 may bepositioned so as to connect the second side port 140 and the outerannular chamber 135. As shown in FIG. 2, in some embodiments, excessmaterial may be removed from the base member 100, such as shown in FIG.2, to reduce weight and cost of manufacturing (e.g., partially hollowedout). As discussed above, in some embodiments, the base member 100 maybe a solid member such that the first channel 120 and the second basechannel 130 are disposed between the first surface 105 and the secondsurface 200 of the base member 100 (i.e., located between the top andbottom of the base member). In some embodiments, excess material may beremoved from the base member 100, such as shown in FIG. 2, to reduceweight and cost of manufacturing.

With reference to FIG. 3, a top view of the base member 100 of FIG. 1 isillustrated with the channels 120, 130. Here, the first surface 105 ofthe base member 100 clearly shows the arrangement of the first basechannel 120 and the second base channel 130. These channels are shownterminating at the inner annular chamber 115 and the outer annularchamber 135, respectively. In addition, the gaskets 110 are shown atopthe first surface 105. The gaskets 110 may be disposed on a top edge ofthe one or more annular walls 145, 150 and may be configured to encircleone or more annular walls defined by a platform member (e.g., annularwalls 505, 510 of platform member 400 in FIG. 5). The gaskets 110 may befurther configured to extend radially inward beyond their respectiveannular wall to prevent air leakage between chambers and channels. Forexample, a gasket 110 disposed atop of outer annular wall 150 of thebase member 100 may extend radially inward such that the gasket 110contacts the outer annular wall 505 of the platform member 400,hereinafter described. In such an example, the gasket 110 maysubstantially seal the outer annular chamber about a linear contactwhich encircles the outer annular wall 505. The gaskets 110 may furtherbe configured to be recessed into the bottom surface of the base member105 such that the gaskets 110 of the base member 100 do not contact thebottom surface 500 of the platform member 400 when the base member 100and platform member 400 abut.

With reference to FIG. 4, a top view of a platform member 400 isillustrated installed on a base member 100. The depicted platform member400 includes a top surface 405, a nozzle 410, one or more notches 415,and a nozzle channel 425. The platform 400 is configured to hold thespecimen thereon and rotate relative to the base member 100. By way ofexample, the platform 400 may rotate 360 degrees relative to the basemember 100 in either direction (e.g., a clockwise and/orcounter-clockwise rotation). Further, the present disclosurecontemplates that any number of full or partial rotations of theplatform 400 may be made relative to the base member 100, in eitherdirection. The nozzle 410 may supply a treatment agent to the specimenas discussed herein. As described in greater detail below, with regardsto FIG. 6, the platform member may define one or more platform channels(e.g., first platform channel 515 and second platform channel 520).

Similarly, with reference to FIG. 5, a bottom view of an embodiment ofthe platform member 400 is illustrated. The depicted platform member 400includes a bottom surface 500, an inner annular wall 510, and outerannular wall 505, a first platform channel 515, a second platformchannel 520, and one or more notches 415. In some embodiments, at leasta portion of the bottom surface 500 of the platform member 400 may beconfigured to abut the first surface 105 of the base member 100 duringoperation. In some embodiments, the bottom surface 500 may define aninner annular wall 510 and an outer annular wall 505. The base member100 may be configured to receive the platform member such that the innerannular wall 510 and the outer annular wall 505 nest in spaced definedby the one or more annular walls 145, 150 defined by the first surface105 of the base member 100. By way of example, when the first surface105 of the base member 100 abuts the bottom surface 500 of the platformmember 400, the outer annular wall 150 of the base member 100 mayencircle the outer annular wall 505 of the platform member 400.Likewise, in such an example, the inner annular wall 145 of the basemember 100 may encircle the inner annular wall 510 of the platformmember 400. Further, in such an embodiment, the connection between theplatform member 400 and the base member 100 may be such that the innerannular chamber 115 is defined radially inward of the inner annular wall510, and the outer annular chamber 135 is defined between the innerannular wall 510 and the outer annular wall 505.

In some embodiments, only one of the base member 100 and the platformmember 400 may define annular walls and/or chambers. In otherembodiments, the base member 100 and/or the platform member 400 may beconfigured to receive one or more annular walls unattached to eithermember. For example, one or more separate wall members may be placedbetween the platform member and base member to create one or morechambers. Additionally, although shown as circular or annular walls, thepresent disclosure contemplates that any shape capable of creating arotatable enclosure or chamber may be used.

With further reference to FIG. 5, one end of the first platform channel515 may terminate in the inner annular chamber 115 located in the spacecreated radially inward of the inner annular wall 510. Similarly, oneend of the second platform channel 520 may terminate in the outerannular chamber 135 located in the space created between the innerannular wall 510 and the outer annular wall 505. The connection betweenthe base member 100 and the platform member 400 may be such that theinner annular chamber 115 and the outer annular chamber 135 may beenclosed and may substantially airtight from one another. The connectionbetween the base member 100 and the platform member 400 may be such thatthe first platform channel 515 and the first base channel 120 may be incontinuous fluid communication. Similarly, the connection between thebase member 100 and the platform member 400 may also be such that thesecond platform channel 520 and the second base channel 130 may be incontinuous fluid communication. By way of example, a fluid supplied tothe first side port 125 may flow through the first base channel 120,into the inner annular chamber 115, and through the first platformchannel 515.

In some embodiments, the connection between the base member 100 and theplatform member 400 may be such that the platform member 400 may rotateabout the base member. In some embodiments, the platform member 400 andbase member 100 may allow unlimited rotation therebetween. The rotationof the platform member 400 about the base member 100 may maintaincontinuous fluid communication between the first base channel 120 andthe first platform channel 515, as well as continuous fluidcommunication between the second base channel 130 and the secondplatform channel 520 for any rotational position of the platform memberrelative to the base member. As discussed above, one or more gaskets 110may facilitate this connection between the base member 100 and theplatform member 400 and help to prevent leakage of fluids supplied tothe apparatus. Additionally, the platform member 400 may define one ormore notches 415 along the edge of the platform member 400 such as tofacilitate user rotation of the platform member 400 about the basemember 100.

With reference to FIG. 6, a bottom view of the platform member 400 isillustrated showing the platform channels 515, 520. As discussed above,the first platform channel 515 is shown terminating on one end radiallyinward of the inner annular wall 510 and the second platform member 520is show terminating on one end between the inner annular wall 510 andthe outer annular wall 505. The ends of the first platform channel 515and the second platform channel 520 opposite the annular chambers mayeach terminate at the top surface 405 of the platform member 400. Asshown in FIG. 4, in some embodiments, the one or more platform channelsmay be in fluid communication with a nozzle channel 425. As shown inFIGS. 5-6, these channels may be located between a top surface 405 and abottom surface 500 of the platform member 400. In some embodiments, theplatform member 400 may be solid such that the first platform channel515 and the second platform channel 520 are enclosed in the body of theplatform member 400.

With reference to FIG. 7, an example nozzle 410 is illustrated affixedatop the top surface 405 of the platform member 400. The nozzle 410 mayinclude a nozzle channel 425, an inner shell 705, an outer shell 710,and a shell channel 715. In the example embodiment shown in FIG. 7, thenozzle channel 425 may be in fluid communication with the first platformchannel 515 and may extend through the outer shell 710 and inner shell705, terminating within the inner shell 705 of the nozzle 410.Additionally, a shell channel 715 may be defined by the space locatedbetween the inner shell 705 and the outer shell 710. In some stillfurther embodiments, the shell channel 715 may be in fluid communicationwith the second platform channel 520. The shell channel 715 mayterminate about a peripheral edge of the nozzle 410, such that asemi-circular opening is defined between the inner shell 705 and theouter shell 710 as shown in FIG. 7. In some embodiments, an anestheticmay be administered to a subject using the nozzle channel 425, and areverse flow (e.g., vacuum or other suction) may be applied to the shellchannel 715 around the nozzle channel 425 to create a self-scavengingsystem whereby fluid is released within the nozzle 410 at an interior ofthe inner shell 705, and the fluid may be drawn into the shell channel715 between the inner shell 705 and outer shell 710 at the peripheraledge. The specimen's head may be positioned in the nozzle 410 internalof the inner shell 705 to receive the fluid treatment agent. Althoughthe example embodiment of FIG. 7 illustrates the nozzle 410 affixed tothe top surface 405 of the platform member 400, the present disclosurecontemplates that the nozzle 410 may be located anywhere in proximity tothe platform member so long as fluid communication between the nozzlechannel 425 and the first platform channel 515 is maintained.

With reference to FIGS. 8-9, cross-sectional views of the base member100 and the platform member 400 are illustrated. In FIG. 8, the firstbase channel 120 is illustrated terminating in the first annular chamber115 in the space radially inward of (bounded by) the inner annular wall145 defined by the first surface 105 of the base member 100. The secondbase channel 130 is illustrated terminating in the outer annular chamber135 in the space created between the inner annular wall 145 and theouter annular wall 150. Gaskets 110 are illustrated atop each of theinner annular wall 145 and the outer annular wall 150. In someembodiments, as previously described, the gaskets may extend radiallyinward beyond their respective annular wall to prevent air leakagebetween chambers and channels.

With reference to FIG. 9, a cross-sectional view of the base member 100and the platform member 400 are shown together. In FIG. 9, the firstplatform channel 515 is illustrated terminating on one end in the innerannular chamber 115 in the space radially inward of the inner annularwall 510. The first platform channel 515 is illustrated terminating on asecond end at a position on the top surface 405 in fluid communicationwith a nozzle channel 425. As discussed above, the nozzle channel 425may be in fluid communication with the first platform channel 515 andmay extend through the outer shell 710 and inner shell 705, terminatingwithin the inner shell 705 of the nozzle 410. The second platformchannel 520 is illustrated terminating on one end in the outer annularchamber 135 in the space created between the inner annular wall 510 andthe outer annular wall 505. The second platform channel 520 isillustrated terminating on a second end at a position on the top surface405 in fluid communication with a shell channel 715. As discussed above,the shell channel 715 may be in fluid communication with the secondplatform channel 520 and may terminate about a peripheral edge of thenozzle 410, such that a semi-circular opening is defined between theinner shell 705 and the outer shell 710 as shown in FIG. 7.

With reference to FIG. 10, a perspective view of a rotatable surgicaltable is displayed with the first surface 105 of base member 100abutting the bottom surface of the platform member 400 (e.g., bottomsurface 500 shown in FIG. 5). As discussed further below, a user mayrotate the platform member 400 relative to the base member 100 throughuse of the one or more notches 415.

With reference to FIG. 11, a bottom view of an alternative platformmember 400 is displayed. In FIG. 11, two electrical contacts 1100 areillustrated disposed on the bottom surface 500 of the platform member400. In some embodiments, the rotatable surgical table may comprise aheated surface (e.g., heated surface 1205 in FIG. 12) disposed on thetop surface of the platform member (e.g., top surface 405 in FIG. 12).The electrical contacts 1100 may correspond to ends of a transmissionmedium (e.g., wire, coil, or the like) disposed within the body of theplatform member 400 and configured to transmit an electrical current. Insome embodiments, the base member 100 may also comprise a transmissionmedium configured to transmit an electrical current. In such anembodiment, the electrical contacts 1100 may be in electricalcommunication with the transmission medium of the base member when thebottom surface 500 platform member 400 abuts the first surface 105 ofthe base member 100. Electrical communication may further be maintainedwhen the platform member 400 is rotated about the base member 100 viaelectric brushes, slip rings, rotary electrical interfaces, rotatingelectrical connectors, collectors, swivels, electrical rotary joints,rotary unions, or the like disposed between the platform member 400 andthe base member 100. In some embodiments, the platform member 400 and/orbase member 100 may be configured to be in electrical communication witha power source (e.g., battery, power outlet, or the like) such that anelectrical current may be provided to the transmission medium.

With reference to FIG. 12, a top view of an alternative platform member400 is illustrated in conjunction with a base member (e.g., base member100 of FIG. 1). In some embodiments, the platform member 400 may furthercomprise a heated surface 1205. As described above, the heated surface1205 may define a pad configured to receive a specimen. The heatedsurface 1205 may, via an electrical current supplied by the transmissionmedium associated with the electrical contacts 1100, generate heat(e.g., via resistors or the like) such that the body temperature of thespecimen may be influenced. In some embodiments, the heated surface 1205(as seen in FIG. 13) may extend into an area covered by the nozzle 410.The present disclosure contemplates that the heated surface 1205 maycover any portion of the top surface 405 of the platform member 400,and/or that heat may be applied to any member or surface of anyembodiment discussed herein.

With continued reference to FIG. 12, the platform member 400 may furtherdefine one or more openings 1210 configured to receive one or morecorresponding posts 1215. The one or more openings 1210 may bepositioned at any location upon the top surface 405 of the platformmember 400. Further, the one or more openings 1210 may be of any depthrequired to secure the location of an object disposed inside the one ormore openings 1210 (e.g., post 1215). As seen in the enlarged areadepicting post 1215, the one or more posts 1215 may be stepped (e.g.,diameters of varying size) such that only a portion of the post 1215 maybe disposed within the body of the platform member 400 when the post1215 is received by an opening 1210.

In some embodiments, the posts 1215 may be configured such that asecuring member (e.g., string, elastic band, or the like) may wraparound the post and specimen in order to secure the specimen to theplatform member 400. In some other embodiments, the posts 1215 may bepositioned such that they form a boundary. By way of example, the one ormore posts 1215 may be disposed about the perimeter of the heatedsurface 1205 in order to limit or otherwise restrict the movement of aspecimen disposed on the heated surface. In some still furtherembodiments, the top surface 405 of the platform member 400 may comprisea rubberized surface at least partially covering the surface of theplatform member 400. By way of example, the rubberized surface maydefine a layer of an elastomer (e.g., rubber or the like) of 3 mm-4 mmin thickness such that a specimen disposed on the rubberized surface maybe pinned to the rubberized surface. Additionally, the rubberizedsurface may also facilitate positioning of a specimen disposed thereonvia the friction between the specimen and rubberized surface resistingthe movement of the specimen during possible rotation of the platformmember 400.

With reference to FIGS. 12-13, an alternative nozzle 410 (e.g., nosecone) for use in some embodiments is illustrated. The nozzle 410, withreference to FIG. 13, may, comprise an inner shell 705, an outer shell710, and a shell channel 715. Similar to the nozzle 410 in FIG. 7,described above, the shell channel 715 may be defined by the spacecreated between the outer shell 710 and inner shell 705, and mayterminate about a peripheral edge of the nozzle 410. Additionally, theshell channel 715 may be in fluid communication with the second platformchannel 520, and may be configured in some embodiments, in conjunctionwith a reverse flow (e.g., vacuum suction) applied to the rotatabletable (via side port 140 discussed above), to create a self-scavengingsystem.

Additionally, in some embodiments as seen in FIG. 13, the nozzle 410 maybe configured without a nozzle channel 425 (as seen in FIG. 4) affixedto the top surface 405 of the platform member 400. In such anembodiment, the nozzle 410 may be configured such that the firstplatform channel 515 terminates at a point disposed on the top surface405 of the platform member 400. The nozzle 410 may further be configuredto cover the first platform channel 515 in order to direct the fluidflow supplied by the first platform channel 515.

With reference to FIGS. 14-15, in some embodiments, an alternativeplatform member may be provided that is comprised of two separablemembers, a top platform member 1400 and a bottom platform member 1500.As seen in FIG. 14, the top platform member 1400 may define a first topplatform opening 1410, a second top platform opening 1405, a bottomsurface 1420, a recessed surface 1425, and a first keying feature 1415.The top platform member 1400 may also be configured to receive a bottomplatform member (e.g., bottom platform member 1500 in FIG. 15). By wayof example, the top platform member may define a recess configured toreceive the bottom platform member 1500 such that the top surface of thebottom platform member (e.g., top surface 1505 in FIG. 15) abuts therecessed surface 1425 of the top platform member 1400. In someembodiments, the thickness of the top platform member (i.e., thedifference between the surface to which the specimen is secured and therecessed surface 1425) may be between 1-3 mm.

In some embodiments, the top platform member 1400 may be configured suchthat the first top platform opening 1410 is in fluid communication withthe first platform channel 515. Additionally, the top platform member100 may be configured such that the second top platform opening 1405 isin fluid communication with the second platform channel 520. In someembodiments, as above, the first top platform opening 1410 may beconfigured to administer an anesthetic to a rodent via a nozzle disposedon the top surface of the top platform member 1400 (e.g., nozzle 410).Additionally, as above, the second top platform opening 1405 may be influid communication with the second platform channel 520 and configuredto provide a reverse suction (e.g. a vacuum suction). This communicationmay create a self-scavenging system via a channel in fluid communicationwith the second top platform opening 1405 disposed about the peripheraledge of a nozzle disposed on the top surface of the top platform member(e.g., shell channel 715 in FIG. 12). The top platform member 1400 mayfurther define a bottom surface 1420 configured to abut a top surface ofa base member (e.g., first surface 105 of the base member 100 in FIG.1).

By way of example, thebottom platform member 1500 may nest within the top platform member 1400such that the top surface 1505 abuts the recessed surface 1425. In suchan example, the bottom surface 1510 of the bottom platform member 1500may be substantially level with the bottom surface 1420 of the topplatform member 1400 such that both the bottom surfaces 1420, 1510 abutthe top surface of a base member, when the separable platform member(e.g., bottom platform member 1500 and top platform member 1400) isreceived by the base member (e.g., base member 100 in FIG. 1).

With continued reference to FIG. 15, in some embodiments, the bottomplatform member 1500 may comprise a heated surface 1205. The heatedsurface 1205 may, via an electrical current supplied by the transmissionmedium associated with the electrical contacts electrical elements 1520,generate heat (e.g., via resistors or the like) such that the bodytemperature of a specimen affixed to a top surface of the top platformmember 1400 may be influenced. By way of example, when the bottomplatform member 1500 is received by the top platform member 1400, theheated surface 1205 may heat (e.g., via conduction, convection, or thelike) the top platform member 1400. The present disclosure contemplatesthat the heated surface 1205 may cover any portion of the top surface1505 of the bottom platform member 1500, and/or that heat may be appliedto any member or surface of any embodiment discussed herein. As above,although described in conjunction with an electrically powered heatingpad, the present disclosure contemplates that heat may be provided to aspecimen from a variety of means (e.g., chemical heat pad, heating lamp,or the like).

In some embodiments, the top surface 1505 may further compriseelectrical elements 1520. The electrical elements 1520 may correspond toa transmission medium (e.g., wire, coil, or the like) disposed withinthe body of the bottom platform member 1500 and configured to transmitan electrical current. As above, in some embodiments, a base member(e.g., base member 100 in FIG. 1) may also comprise a transmissionmedium configured to transmit an electrical current. In such anembodiment, the electrical elements 1520 may further include electricalcontacts (e.g., electrical contacts 1100 in FIG. 11) disposed on thebottom surface 1510 of the bottom platform member 1500. The electricalelements 1520 may be in electrical communication with a transmissionmedium of the base member when the bottom surface 1510 bottom platformmember 1500 abuts the first surface 105 of the base member 100.Electrical communication may further be maintained when the separableplatform member (e.g., bottom platform member 1500 and top platformmember 1400) is rotated about a base member via electric brushes, sliprings, rotary electrical interfaces, rotating electrical connectors,collectors, swivels, electrical rotary joints, rotary unions, or thelike disposed between the separable platform member and the base member.In some embodiments, the bottom platform member 1500 and/or base membermay be configured to be in electrical communication with a power source(e.g., battery, power outlet, or the like) such that an electricalcurrent may be provided to the transmission medium.

With continued reference to FIGS. 14-15, the top platform member 1400and the bottom platform member 1500 may further define a first keyingelement 1415 and a second keying element 1515, respectively. Thesekeying elements may be configured such that the top platform member 1400may only receive the bottom platform member 1500 in a definedorientation. By way of example, the first keying element 1415 may definea 9-sided polygon and the second keying element 1515 may define acorresponding 9-side polygon. In such an example, the keying elementsmay be configured to assist the top platform member 1400 receiving thebottom platform member 1500 in an orientation such that the first topplatform opening 1410 and second top platform opening 1405 may be influid communication with the first platform channel 515 and secondplatform channel 520, respectively. Although illustrated in FIGS. 14-15as a 9-side polygon, the present disclosure contemplates that the firstkeying element 1415 and the second keying element 1515 may define anynumber of shapes without limitation. In some embodiments, the firstkeying element 1415 and second keying element 1515 may each definecorresponding unique shapes such that the top platform member 1400 mayonly receive the bottom platform member 1500 in an orientation in whichfluid communication is maintained between the bottom platform member1500 and the top platform member 1400.

Example Operation and Method

As will be appreciated by the description above, the rotatable surgicaltable, systems, and methods described herein may be used to process(e.g., treat, operate on, dissect, etc.) a specimen (e.g., a rat orother rodent or small animal). In an example embodiment shown in FIGS.1-7, a specimen may be affixed to the top surface 405 of the platformmember 400. The first side port 125 of the base member 100 may besupplied with an anesthetic or other treatment agent. This first sideport 125 may be connected to a supply (e.g., storage tank) via one ormore connectors (e.g., medical tubes) that engage the first side port.The first side port 125 may be in fluid communication with the firstbase channel 120, located in the base member 100, such that theanesthetic flows from the anesthetic supply, through the connector andinto the first base channel 120 via the first side port 125. The basemember 100 may be configured to receive and/or otherwise connect withthe rotatable platform member 400. At least one of the base member 100and the base member 400 may define one or more annular walls. Theconnection between the base member 100 and the platform member 400 maybe such that the platform member 400 abuts (e.g., rests atop) the basemember 100. In the example embodiment, the annular walls 505 510 of theplatform member 400 nest within the base member 100.

In the example embodiment, the connection between the base member andthe platform member further defines an inner annular chamber 115 and anouter annular chamber 135. The inner annular chamber 115 may be in fluidcommunication with the first base channel 120. The platform member 400may further define a first platform channel 515 in fluid communicationwith the inner annular chamber 115, and in fluid communication with thefirst base channel 120. Therefore, the treatment agent may flow from thefirst base channel 120 through the first platform channel 515 via theinner annular chamber 115. In the example embodiment, the first platformchannel 515 may terminate at a position on the top surface 405 of theplatform member. Further, this first platform channel 515 may be influid communication with a nozzle channel 425. This nozzle channel 425may receive the treatment agent (e.g., a gaseous anesthetic) flowingfrom the first platform channel 515 and dispose of the anesthetic to aspecimen via the nozzle 410.

Similarly, the second side port 140 of the base member 100 may besupplied with a reverse flow (e.g., vacuum or other suction). Thissecond side port 140 may be connected to a supply (e.g., storage tank)via one or more connectors (e.g., medical tubes). The second side port140 may be in fluid communication with the second base channel 130,located in or attached to the base member 100, such that a reverse flowremoves fluid from the second base channel 130 via the second side port140. As discussed above, the base member 100 may be configured toreceive and/or otherwise connect with the platform member 400 and maydefine one or more annular walls.

In the example embodiment, the connection between the base member andthe platform member defines an outer annular chamber 135. The outerannular chamber 135 may be in fluid communication with the second basechannel 130. The platform member 400 may further define a secondplatform channel 520 in fluid communication with the outer annularchamber 135, and inherently in fluid communication with the second basechannel 130. Therefore, the reverse flow may draw fluid from the secondplatform channel 520 to the second base channel 130 via the outerannular chamber 135 and out the side port 140. In the exampleembodiment, the second platform channel 520 may terminate at a positionon the top surface 405 of the platform member. Further, this secondplatform channel 520 may be in fluid communication with a shell channel715 between the inner shell 705 and the outer shell 710. This shellchannel 715 may be disposed around the edge of the nozzle 410 and may bein fluid communication with the second platform channel 520.Accordingly, a reverse flow may be applied to the shell channel 715 viathe second platform channel 520. The reverse flow or suction applied atthe shell channel 715 around the nozzle 410 and nozzle channel 425 maycreate a self-scavenging system. As would be appreciated by one ofordinary skill in the art in light of the present disclosure, theself-scavenging system may be reversed, such that the treatment agent isreleased from the shell channel 715 and excess agent is drawn into thenozzle channel 425 by the reverse flow.

The example method of processing a specimen using the rotatable surgicaltable includes supplying an anesthetic via the first side port 125through the first base channel 120, the inner annular chamber 115, thefirst platform channel 515, and the nozzle channel 425, and isadministered to the specimen. A reverse flow (e.g., a pump or suction)may be applied to the second side port 140 such that the air or fluidlocated about the shell channel 715 enters the shell channel 715, flowsthrough the second platform channel 520, the outer annular chamber 135,the second base channel 130, and to a reverse flow supply (e.g., a pump)via the second side port 140.

Additionally, during processing of a specimen, the above describedconnection between the platform member 400 and the base member 100 isconfigured to allow the platform member 400 to be rotated about the basemember 100 while maintaining continuous fluid communication between theabove described channels at any angle and for any number of rotations.The annular chambers may be arranged concentrically, such that eachannular chamber is positioned a predetermined radial distance from therotational center of the platform/base interface. Such an arrangementmay facilitate the unlimited rotational connectivity of the embodimentsdescribed herein. One or more gaskets may be located between the basemember 100 and platform member 400 to facilitate maintaining fluidcommunication and prevent air leakage at the interface between theplatform 400 and the base 100. Further, the platform member 400 may benotched (e.g., notches 415) to assist the user is effectuating therotation of the platform member 400 about the base member 100.

The present disclosure contemplates that the present invention may becreated from any suitable material known in the art (e.g., plastic,resin, ceramic, metal, rubber, or the like). By way of example, thepresent invention may be created through 3-D printing, injectionmolding, among others without limitation. Additionally, due to the oftrequired sterile nature of medical environments, the present disclosurecontemplates that the present invention may be comprised of bacterialresistant materials or subjected to any manner of sterilizationprocedure or device (e.g., an autoclave). Although the present inventionis depicted as two members (e.g., a base member and a platform memberwith an attached nozzle), the present disclosure contemplates that thepresent invention may be comprised of any number of individual membersor pieces so long as continuous fluid communication is maintainedbetween the respective channels.

In embodiments discussed herein, a treatment agent is provided throughone or more of the channels to the nozzle. In some embodiments, thetreatment agent may be an anesthetic, such as, for example, vaporizedisoflurane.

Many modifications and other embodiments of the inventions set forthherein will come to mind to one skilled in the art to which theseinventions pertain having the benefit of the teachings presented in theforegoing descriptions and the associated drawings. For example, thebase member and platform member shown and described herein each includetwo channels, which in some embodiments may respectively supply atreatment agent and apply a reverse flow to the nozzle. In someembodiments, only one channel may be provided that supplies a treatmentagent or applies a reverse flow. In some other embodiments, three ormore channels may be provided to apply multiple treatment agents,multiple reverse flows, or combinations thereof. In instances havingthree or more channels, three or more annular chambers may be likewisearranged in concentric positions in a similar manner to the embodimentsshown in FIGS. 1-7.
